Abstract (en)
[origin: EP0382680A1] In a method for cryptographically processing data in a cryptographic system (100), the process takes place at two levels (1 and 2). At the first level (1), the data transmission protocols (PR) are detected within the data set (DM) or cryptotext set (SM). The clear text (KT) or the cryptodata (CT) are cryptographically processed separately at the second level (2) and then re-combined at the first level (1) with the data transmission protocols (PR). <IMAGE>
